How long will it take to be back again?

A: Zipline.io probably is not coming back.

Full answer with alternatives:

In late October 2020, Quantopian's founder/CEO John Fawcett announced that they would be winding down their free community offering and the site was shut down in mid November 2020. The underlying technology for Quantopian was called Zipline, which allowed individual users to download the code and run their own trading systems (it required additional data for it to operate). The entire project was open sourced, with source code being available on Github. The documentation for Zipline was provided on Zipline.io.

Certain staff were going to Robinhood, but there was no direct indication that RH were going to continue any aspect of Quantopian.

In Nov 2020 Quantopian.com went offline.

In Feburary 2021, Zipline.io went quiet - possible either the hosting went unpaid and/or the domain expired.

Since the initial communication given by Quantopian by closed they have not communicated regarding open issues or provided any further guidance on any mailing list. There have been no further changes to the source code but ownership of the project on Github still remains with them. Nobody can make any direct changes to their code. The Zipline project that is in stasis is here:
https://github.com/quantopian/zipline

Given we have had radio silence from Quantopian since Oct 2020, and their domains/web sites have lapsed without even just a basic landing page, I don't think that it will come back at all.

However, by virtue of being an open source project, means that the project could be duplicated (forked) - and a number of parties have done this.

The most advanced version, in terms of modernizing Zipline so it supports current versions of Python and other packages such as Pandas, has been done by Stefan Jansen. He advanced the version to 2.0 and dubbed it "Zipline Reloaded", and also updated various other packages that Zipline relies upon too.
The source code can be found here:
https://github.com/stefan-jansen/zipline-reloaded
and documentation here:

and announced here:

Another fork of Zipline is Zipline Trader (by Shlomi Kushchi) which has taken a different approach to bundle management and data storage:

I hope that helps.

Yes, I agree with @RichardDale above.

Yet another fork (slightly older, yet useful) for live trading, with documentation and further history of zipline is at :
